Hello,
I can help you out here, but it is not possible to edit a script and put it in your theme out of the box in WordPress.
You have to first deregister the script using WordPress’s wp_deregister_script:
https://codex.wordpress.org/Function_Reference/wp_deregister_script
Then enqueue the edited script using wp_enqueue_script:
https://codex.wordpress.org/Function_Reference/wp_enqueue_script
The name of the script as registered with WordPress is:
tribe-events-bar
Let me know if you have any follow up questions.
Thanks
